Enhanced visible light photocatalytic activity of Gd-doped CeO2 nanoparticles (NPs) is experimentally demonstrated, whereas there are very few reports on this mechanism with rare earth doping. All-pure and NPs synthesized using a coprecipitation method characterized X-ray diffraction (XRD), absorption spectroscopy, surface-enhanced Raman Spectroscopy (SERS), photoelectron spectroscopy (XPS), superconducting quantum interference device (SQUID). The effect Gd-doping properties discussed along...
This article reports on reversible manipulation of room temperature ferromagnetism (RTFM) in nondoped bulk CeO2. The magnetization measurements establish that paramagnetic CeO2 is driven to a ferromagnetic state, without change structure, when vacuum annealed at 600 °C. Ce ions transform from 4+ 3+ accompanied by evolution oxygen vacancies (VO) during the RTFM transition, as determined x-ray photoemission. F+ centers (the electrons singly occupied vacancies) play key role exchange mechanism....
In this work, we demonstrate that room temperature ferromagnetism can be induced in pristine anatase TiO2 paramagnetic bulk powder through extended hydrogenation. Defect complexes, Ti3+–VO (Ti3+ ions accompanied by oxygen vacancies) are clearly identified hydrogenated combining x-ray diffraction and photoemission spectroscopy. The observed ferromagnetic ordering is reversible switched between “on” “off” inducing or removing, respectively, these defect complex. We convincingly elucidate the...
